This propeller is an absolute must for the Science Olympiad Wright Stuff or TSA competitor. It is 9" in diameter and the total weight of the propeller assembly is 2 grams. It features a low friction propeller shaft assembly including a bead. This propeller will spin extremely slow while providing the necessary thrust.

By using this propeller you can increase your flight times easily by more than a minute. This propeller also flies with less power which means that you can use a thinner rubber motor and thereby get more winds into that motor. We strongly recommend that you use our CF-M1 (Competition motor pack) to extract maximum performance from your ultimate competition prop. If you use this prop with our CF-M1 rubber motor competition pack you can extend your regular flight time by over two minutes.
